An implant (1) is designed to be fitted in a hole (2a) formed in jaw bone (2) and soft tissue (3). The implant comprises a portion (4b') to be placed against the upper edge of the jaw bone. Along most of its peripheral extent, the portion (4b') is provided with grooves (9, 9') or recesses designed to stimulate bone movement and ingrowth (10) of bone. The bone ingrowth (10) forms a barrier against substantial or visible subsidence, around the portion, of the bone (2) with overlying soft tissue (3). The invention permits a good esthetic result and prevents bacteria from penetrating into the internal parts of the implant and of the hole.
